With or without your help

I honestly do not know what people expect from a sixteen year old. I do not know how old you all are, but I was sixteen, seven years ago. And till this day when I come across somethings I wrote then, maybe a text, or I remember an activity, all I can do is cringe, and I try to believe it wasnt me that said, or wrote somethings. A sixteen year old is a child. There is only a four year old gap between my sister, and I and I do not see her as an adult. You were only eighteen last year, and that is just "legal age." Also, because who I was four years ago isn't who I am now, and I know when she is twenty three she will wonder why she did somethings she is doing now. Teenagers are teenagers, and I do not know if you want an unrealistic book with a thirty year old living in the body of a sixteen year old.
